[0054] Furthermore, the flow meter 6011, the first solenoid valve 6012 and the first pressure relief valve 6013 are sequentially arranged on the main pipe 600 from the water inlet 601 to the water outlet 602; the first one-way valve 6021 and the first liquid level detection probe 6061 are respectively located on the first delivery pipe 6001 on both sides of the first delivery pump 701, and the first one-way valve 6021 is located on the first delivery pipe 6001 between the first delivery pump 701 and the main pipe 600; the second one-way valve 6022 and the second liquid level detection probe 6062 are respectively located on the second delivery pipe 6002 on both sides of the first delivery pump 701, and the second one-way valve 6022 is located on the On the second delivery pipeline 6002 between the first delivery pump 701 and the main pipeline 600; the third one-way valve 6023 and the third liquid level detection probe 7021 are respectively located on the third delivery pipeline 6003 on both sides of the second delivery pump 702, and the third one-way valve 6023 is located on the third delivery pipeline 6003 between the second delivery pump 702 and the main pipeline 600; the fourth one-way valve 6024 and the third liquid level detection probe 7021 are respectively located on the fourth delivery pipeline 6004 on both sides of the third delivery pump 703, and the fourth one-way valve 6024 is located on the fourth delivery pipeline 6004 between the third delivery pump 703 and the main pipeline 600.

[0055] In this embodiment, the one-way valve and the liquid level detection probe on each delivery pipeline have the same structure and function. The delivery pump, the main pipeline 600, the delivery pipeline, and the components on the delivery pipeline are all arranged in the delivery device body 6. After the user completes the selection of delivery liquid in the operation panel or the software program, the main controller controls the corresponding delivery pump to start working and deliver the detergent in the liquid storage bottle into the main pipeline 600. Tap water flows into the main pipeline 600 from the water inlet 601 and flows out from the water outlet 602, and at the same time, the detergent is diluted and flushed into the washing equipment to complete the delivery of detergent.

[0056] The following takes the example of dispensing detergent from the first liquid storage bottle 1. Tap water enters the main line 600 from the water inlet 601, and the flow meter 6011 installed in the main line 600 monitors the water flow state in the main line 600. The first solenoid valve 6012 is used to control the water flow. When the user chooses to dispense detergent, the washing device opens the solenoid valve, and the tap water flows in the main line 600. The flow meter 6011 transmits the water flow information to the controller, and then the controller closes the first solenoid valve 6012 to cut off the water flow. After the water flow is cut off, the pressure in the main line 600 at the rear end of the first solenoid valve 6012 decreases, and the first dispensing pump 701 starts to dispense detergent into the main line 600.

[0057] When the detergent is put in, the controller opens the first solenoid valve 6012 again, and the tap water dilutes the detergent in the main line 600 and flushes it into the washing device to start washing. In order to prevent high-pressure tap water from flowing into the dosing pump and the liquid storage bottle along the main line 600, a one-way valve is installed between the dosing pump and the main line 600 to prevent tap water from entering the dosing pump and the detergent storage bottle. In order to eliminate the negative pressure water hammer caused by the sudden closure of the first solenoid valve 6012 during the water intake process, a pressure relief valve 6013 is installed at the rear end of the first solenoid valve 6012 to add air to the main line 600 to balance the pressure.

[0058] In some embodiments, a liquid storage tank 606 is provided in the main body 6 of the dispensing device, and a liquid storage tank cover 607 is installed on the liquid storage tank 606. The first liquid storage bottle 1 and the second liquid storage bottle 2 are respectively invertedly installed on the two liquid storage tank covers 607, and the liquid storage tank cover 607 is provided with a liquid storage tank pipe 6071 connecting the liquid storage tank 606 and the first liquid storage bottle 1 and the second liquid storage bottle 2; the first liquid level detection probe 6061 and the second liquid level detection probe 6062 are arranged on the liquid storage tank 606, and the bottoms of the first liquid level detection probe 6061 and the second liquid level detection probe 6062 are respectively lower than the bottle mouths of the first liquid storage bottle 1 and the second liquid storage bottle 2.

[0059] Take the first liquid storage bottle 1 as an example. When the first liquid storage bottle 1 storing detergent is installed on the liquid storage tank cover 607, the detergent will flow into the liquid storage tank 606 along the liquid storage tank pipe 6071 of the liquid storage tank cover 607. When the detergent liquid level in the liquid storage tank 606 reaches the mouth of the first liquid storage bottle 1, the liquid level will seal the bottle mouth, and the liquid in the bottle will stop flowing out. As the user uses it, the detergent level in the liquid storage tank 606 decreases, the bottle mouth is exposed again, and the detergent in the bottle flows out again until it covers the bottle mouth again. A first liquid level detection probe 6061 is provided on the liquid storage tank 606, and the bottom of the first liquid level detection probe 6061 is lower than the bottle mouth. When the detergent stock in the liquid storage tank 606 is lower than the warning height at the bottom of the first liquid level detection probe 6061, the device will issue a warning to remind the user to replenish the detergent in time.
